Anti-Masonic Party

The Anti-Masonic Party was a liberal party in the United States that existed from 1828 to 1838, being the first "third party" in US history. The party was founded in response to the murder of William Morgan by the Freemasons, which had occurred after he betrayed their dealings to the press. Notable party members were former President of the United States John Quincy Adams and future Secretary of State William H. Seward, and the party joined the like-minded American Whig Party in 1838.
